CREAM SEPARATOE.

Application filed fipril 8,

T all whom it may concern:

Be it known that 1., PETER C. FPHILIP, a citizen of the United States, and a resident of Bowlus, in the county of Morrison and Stats 0'5 Minnesota, have invei'ited certain new and useful Improvements in Cream fieparators of which the following is a specification.

This invention relates to separators especially adapted for separating liquids having different specific gravities.

An important object of this invention is to provide a cream separator having novel means whereby the richness of the cream may be readily regulated by a simple adjusting means within convenient reach of the operator.

A further object is to provide a cream separator having simple means whereby the same may be taken apart tor the purpose of cleaning and which may be readily assembled.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings Figure l is a plan view of the improved separator.

Figure 2 is a vertical sectional view through the same.

Figure 8 is a horizontal sectional view through the separator.

Figure 4': is a horizontal sectional view illustrating a modified form of invention.

In the drawings the numeral 5 generally designates the improved separator which consists of upper and lower disks 6 and 7 respectively the lower disk being provided with a spiral dividing member 8 having a plurality of spaced convolutions which constitute a means for separating the cream from the skimmed milk. The upper portions of the convolutions of the divider are provided with enlargements 10 having grooves which receive washers 11 forming a means for providing a liquid tight connection between the upper disk 6 and the divider 8.

As illustrated in Figure 2 a pipe 12 is extended through the bowl formed by the upper and lower disks and the divider and the said pipe extends for a substantial distance above the upper disk 6 so as to form 1922. Serial No. 550,805.

an inlet means for the milk to be separated.

A suitable spigo mouth oi the pipe is connected to a a pipe 17. will be observed of the pipe 12 is With reference to t 14 is extended into the 12 and the said spigot 16 by means of Figure 2, it that the extended portion exteriorly screw threaded milk tank for engagement with a nut 20 which forms means for urging into engagement the upper disk 6 firmly with the divider which may be formed integral with or otherwise securely connected When desired, the

The inner convolution of the dlvider is secured to the pipe volution is secured tion so as to prevent the escape is rotated. As illustrated when the bowl in Figures 2 and 12 while the outer conto the adjacent convoluof the milk 3, a wing 22 is secured to the outer convolution adjacent a terminal portion of the same and with relation to means of a set s may be adjusted the outer convolutions by crew 24: threaded through the outer convolution. That is to say, the wing 21 is adjustable in the spiral trough which receives the liquid to be separated and as the cream flows ad acent the outer walls of the convolutions the wing 22 may be adjusted with relation ing the richness to the cream for varyof the same. As is well known the difference in the specific gravity 0 between the milk milk to separate and the cream causes the from the cream when subjected to the centrifugal force incident to the rotation of outlet pipes 27 nected to the div partments termed by the bowl. and 28 respectively are con- Milk and cream ider at the discharge comthe wing 22 and form a means whereby the milk and the cream may be conveyed to suitable receivers. In

the form oi? the invention illustrated in Fig; ure 4: the bowl 30 is provided with spaced annuli 31 which form a divider for separating the cream from the milk. The divider is supplied with liquid from a radially arrangedconduit 32 extending from a centrally arranged channel which re with a wing 34: having its 33. The trough or the milk is provided terminal portion pipe ceives in engagement with a set screw 36 which provides a means whereby the wing may be adjusted for varying cream.

In the form 0 the thickness of the f the invention illustrated in Figure 5, the upper and lower disks 40 and 41 respectively may be dished so that the liquid will flow more readily. That is to say, by reason of inclining, the upper and lower disks downwardly toward their outer the liquid outwardly is of disks, a divider arranged between said disks and having a plurality of convolutions, the outer convolution of which is secured to the adjacent convolution to form a closure, a wing secured to the outer convolution adjacent the end of the same, and

separate outlets for the skim milk and the cream.-

3. A cream separator comprising a divider having, a plurality of convolutions,

the outer convolution being secured to the ad acent convolution to form a closure, and 'a wing arranged between the outer convo1ution and the forming the separating element, there being outlets for the skimmilk and the cream;
